Insights
Catheter obstruction in peritoneal dialysis (PD) can cause technique failure. A new angiographic guidewire technique successfully removed intraluminal clots, offering a potential solution for persistent PD catheter issues.
Area of Science:
- Nephrology
- Medical Devices
- Surgical Techniques
Background:
- Catheter obstruction is a significant complication in peritoneal dialysis (PD), leading to dialysate flow problems.
- Failure of conservative management can result in PD technique failure and loss of catheter function.
Purpose of the Study:
- To present a novel technique for managing intraluminal clot obstruction in PD catheters.
- To evaluate the efficacy of an angiographic guidewire in resolving refractory PD catheter blockages.
Main Methods:
- Two cases of PD catheter obstruction due to intraluminal clots were identified.
- A new technique utilizing an angiographic guidewire was employed to remove the obstructive clots.
Main Results:
- Conservative management failed to resolve the catheter obstruction in both reported cases.
- The angiographic guidewire technique successfully removed the intraluminal clots, restoring catheter patency.
Conclusions:
- Intraluminal clots are a cause of PD catheter obstruction.
- Angiographic guidewire intervention presents a viable option for treating PD catheter obstruction when conservative methods fail.
Abstract:
Catheter obstruction is a major cause of dialysate flow problems in peritoneal dialysis (PD). It will lead to PD technique failure, when its conservative management such as vigorous instillation of dialysate occasionally fails to salvage the catheter potency. In this report, we present two cases of catheter obstruction caused by intraluminal clots of PD catheter. The clots, which could not be removed by the conservative management, were removed by a new technique using an angiographic guidewire. The technique could be an option to resolve PD catheter obstruction.
